Midbrain structures involved in motor coordination, notably part of the pathway for voluntary movements.

Auditory Pathways

The neural pathways that carry auditory information from the ears to the brain for processing and interpretation.

Motor Activities

Physical actions and movements generated by the muscle systems under control of the nervous system.
